3.1. Key Component Identification
As shown in “Figure 1”, Hatch X-Ray is comprised of the following components:
1. Base Unit
The Base Unit provides mounting support for the Extension arm and scissor
arm with attached tube-head. It provides system power connection and
application via the Mains Power Line Cord and the Mains Power ON/OFF
Switch. Overall operational control for Hatch X-Ray is also provided via the
Keypad Console.
2. Keypad Console
The Keypad Console is the user/machine interface providing all functional
operating control of the Hatch X-Ray system. Consisting of an LCD display
and keypad, the console keypad allows both automatic and manual selections
of exposure parameters while the resultant operation status is shown via the
LCD display.
3. Extension arm
The Extension arm provides the horizontal space away from the wall-mounted
Base Unit. Available in 15, 24 and 33 - inch lengths to meet the reach
requirements of the installation site.
4. Scissor Arm
The Scissor Arm consists of a vertical and horizontal arm joined via a double
joint. This design enables smooth linear and upward motion transitions while
allowing the attached tube-head to remain balanced in all positions.
5. Tube-head with Beam Limiting Device
Provides 60 kV – 70 kV voltage range (adjustable in 1 kV steps) and 4 mA – 8
mA current range (adjustable in 1 mA steps) to reduce exposure times and the
amount of radiation absorbed by the patient. The tube-head is equipped with a
beam limiting device with a 23 cm (8.98 inches) source to skin distance and 6
cm (2 ⅜ inches) beam diameter at the output. The tube-head is connected to
the arm by means of a rotating contact, allowing 540 degree horizontal rotation
and 310 degree vertical rotation.
